Application filed February 26, :1926. Serial No 90,808.

My present invention has reference to' metal caps adapted for usetoclose or seal bottlesyand the construction is of the type 7 2 ofordinary devices for this purpose.

To the attainment of the foregoing the invention consists in theimprovement as hereinafter described and definitely claimed.

. In the drawings:

Figure 1 is a side elevation of the" neck portion of a bottle sealed inaccordance with this invention.

Figure 2 is a sectional view on the line 2--2 of Figure 1.

Figure 3 is a top plan view of the cap. 7

Figure 4 is a side elevation showing the top of the cap compressed tospread the flange side or skirt thereof to permit the removal of the capof the bottle.

Figure 5 is a sectional view through the vconstruction disclosed inFigure 4. p

The neck 1 of a bottle is provided with the usual outstanding bead 2,and the, ing disc. in each cap, and the skirt of the inouth of thebottle neck is designed to be closed by a cap or seal in accordance withthis invention. v I

The bottle cap is constructed of metal and is of the t pe, commonlyknown as the crownseal. T e cap is of course round-in plan, and has itstop dome or cone-shaped, as at 3. The side or skirt 4 of the cap is'rounded outwardly and from thence inwardly and the lower portion of theskirt is crimped, as at 5, to add to the resilienc of the ripping effectof the skirt on the ad The skirt has its sides at diametrically oppositepoints slitted transversely, as at 6, and the conical top of the cap isformed with radial ribs 7 which materially reinforce not only the topbut the whole of the cap and sustain the concaved upper portion of theskirt in tight gripping engagement with the bead'2 ofthe bottle neck 1.The cap carries an inner disc 8 of cork, or similar compressiblematerial to insure an air tight joint between the cap and the mouth ofthe bottle. 3

My im rovement maybe applied on a bottle wit the usual capping machine,but a pressure by'the hand of an operator may the cap to eflec-' directpressure be found suflicient to appl tively, seal the bottle. upon theapex of the top 3 will com ress the top and consequentlyexpand the s 'rtportion of the cap and the expansion of the latter being materiallyaided by slitting the skirt, so. that the cap may be easily and.

quickly removed from the bottle neck withfor this purpose..

Having described the invention, I claim: A bottle closure or sealcomprising a thin metal cap havin a locking skirt adapted to engage thebe ed mouth of a receptacle,

the top of the cap being conical and the said top being formed withradially ar-' ranged reinforcing ribs, a compressible seal- 3 tore.
